Here's how to use it in different grammatical contexts:
* Nominative singular: γράμμα (gramma) - "letter"
* Genitive singular: γράμματος (grammatos) - "of a letter"
* Dative singular: γράμματι (grammati) - "to a letter"
* Accusative singular: γράμμα (gramma) - "letter" (direct object)
* Vocative singular: γράμμα (gramma) - "letter" (direct address)
Example:
* Το γράμμα είναι στο τραπέζι. (To gramma einai sto trapezi.) - "The letter is on the table."
* Η γραφή του γράμματος είναι όμορφη. (I grafi tou grammatos einai omorfi.) - "The handwriting of the letter is beautiful."
Note: The word "gramma" can also refer to a written character or symbol in general, not just a letter of the alphabet.
